C#命名方法委托的基础引用

示例

在将命名方法分配给委托时，如果满足以下条件，则它们将引用相同的基础对象：

• 它们是相同的实例方法，在类的相同实例上

• 它们是类上的相同静态方法

  public class Greeter
  {
      public void WriteInstance()
      {
          Console.WriteLine("Instance");
      }
      public static void WriteStatic()
      {
          Console.WriteLine("Static");
      }
  }
  // ...
  Greeter greeter1 = new Greeter();
  Greeter greeter2 = new Greeter();
  Action instance1 = greeter1.WriteInstance;
  Action instance2 = greeter2.WriteInstance;
  Action instance1Again = greeter1.WriteInstance;
  Console.WriteLine(instance1.Equals(instance2)); // 假
  Console.WriteLine(instance1.Equals(instance1Again)); // 真正
  Action @static = Greeter.WriteStatic;
  Action staticAgain = Greeter.WriteStatic;
  Console.WriteLine(@static.Equals(staticAgain)); // 真正
